MiMo-V2.6 update targets repetitive tool calls

Xiaomi’s MiMo developers say a training penalty applied only after more than 32 tool calls per turn, leaving shorter bouts of repetition unchecked. They say they trained a repetition-focused reinforcement-learning teacher in 12 steps on about 7,000 examples and merged it into MiMo-V2.6 via MOPD at roughly 4% of the cost of a full mixRL retrain. The team reports that repetition dropped while benchmarks held steady, and says the updated models are open-sourced.
